I am in the process of migrating from a legacy Avaya ACD/IVR platform to Skype for Business 2019 On-premise deployment,

Currently the Avaya platform offers a user facing console that allows on-call numbers to be updated on-demand.

What I am wondering is what options there are to maintain or improve upon this flexibility.

The goal would be that when callers reach the given routing endpoint, the call is sent to the on-call resource. This resource may be assigned all week or a single day or even a couple hours for coverage.

I think I understand what you're looking for Jeffrey. It's a pretty simple feature to have the ability to change the ring-to number... and most phone systems will give you that ability, although the interfaces might be different.

Question: What is the reason behind migrating to an on-prem S4B system? S4B is being replaced by Teams, so just wondering why you'd want to go through that transition, just to move to a product that's been marked for obsolescence.

Is there a reason why your company doesn't want to move to either Teams Phone System or a hosted PBX service provider? Those would be the two most popular choices.

PM me if you'd like to chat and get my recommendations on the best vendors to quote. As an enterprise telecom broker for 17 years, I know all the vendors and can give you some good insight on which solutions our customers have been happy with.

In the meantime, here is some provider-agnostic content you might find useful:

The question comes up a lot, but the short statement is that I work for a utility and was the planned deployment. We will be moving to a teams Hybrid deployment at 8-10 months from now.

Again, the key for me is to avoid groups having to open a request to change every time they want to change who is on-call. I have thought about a managed group, but that would only be valuable during operational hours.
